We +believe that there is a bug in Thrift itself that occasionally causes +a segfault when shutting down the server. If you run into a problem +when shutting down an application running ControlPort, this might be +the cause. If so, we have included a patch with the source code in +this directory that should be applied to Thrift before rebuilding the +Thrift library: + +thrift-codebase-shutdown-patch.diff + +Note that we are working off Thrift version 0.9.2, so this patch may +not be relevant or even cleanly apply in later versions of Thrift. + +We are also still trying to track down another shutdown problem with +Thrift that again appears to be related to their code. If a segfault +persists after the above patch is applied to Thrift, do a backtrace in +GDB to see what the error looks like. If it is different than the +following backtrace, definitely report it to the Discuss GNU Radio +Mailing List as a known bug. If you see the same backtrace as here, +this is a known bug that occurs very irregularly, but help in tracing +down the cause is appreciated. + +#0 0x00007f07b5b478c2 in ??
